Abstract
Disclosed here is a method for producing a decolorizable electrophotographic toner, comprising mixing a first dispersion liquid in which a colorant is dispersed in an amount such that the content of the colorant in the toner is from 5% to 35% by weight, with a second dispersion liquid in which particles containing at least a binder resin and having a volume average particle diameter of 500 nm or less are dispersed, aggregating the colorant and the particles containing at least the binder resin, thereby obtaining aggregated particles, fusing the aggregated particles at a temperature lower than a completely decolorizing temperature of the colorant to obtain the toner, and measuring the number ratio of particles having an equivalent circle diameter of 0.6 μm or more and 2.5 μm or less of the toner using a flow particle image analyzer after the toner is subjected to a stirring treatment.
